# Hardcoding version into SRC_URI because I have no idea at all how upstream is going to version this
# the tarball is -2.6, but there are also references to this release as -1.0
# Fetching LLVM as well: see http://llvm.org/bugs/show_bug.cgi?id=4840

# TODO: I don't think there are any non-system deps, but verify that
# Note: for LTO support, clang will depend on binutils with gold plugins, and LLVM built after that - http://llvm.org/docs/GoldPlugin.html
